.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIacceptor_lifetime\fR\fR
.ad
.RS 22n
The number of seconds that the credential is capable of accepting security
contexts under the specified mechanism. If the credential can no longer be used
to accept contexts, or if the credential usage for this mechanism is
\fBGSS_C_INITIATE\fR, this parameter will be set to \fB0\fR. Specify \fBNULL\fR
if this parameter is not required.
.RE

.sp
.ne 2
.na
\fB\fIcred_handle\fR\fR
.ad
.RS 22n
A handle that refers to the target credential. Specify
\fBGSS_C_NO_CREDENTIAL\fR to inquire about the default initiator principal.
.RE

.sp
.ne 2
.na
\fB\fIcred_usage\fR\fR
.ad
.RS 22n
How the credential may be used with the specified mechanism. The
\fIcred_usage\fR parameter may contain one of the following values:
\fBGSS_C_INITIATE\fR, \fBGSS_C_ACCEPT\fR, or \fBGSS_C_BOTH\fR. Specify
\fBNULL\fR if this parameter is not required.
.RE

.sp
.ne 2
.na
\fB\fIinitiator_lifetime\fR\fR
.ad
.RS 22n
The number of seconds that the credential is capable of initiating security
contexts under the specified mechanism. If the credential can no longer be used
to initiate contexts, or if the credential usage for this mechanism is
\fBGSS_C_ACCEPT\fR, this parameter will be set to \fB0\fR. Specify \fBNULL\fR
if this parameter is not required.
.RE

.sp
.ne 2
.na
\fB\fImech_type\fR\fR
.ad
.RS 22n
The mechanism for which the information should be returned.
.RE

.sp
.ne 2
.na
\fB\fIminor_status\fR\fR
.ad
.RS 22n
A mechanism specific status code.
.RE

.sp
.ne 2
.na
\fB\fIname\fR\fR
.ad
.RS 22n
The name whose identity the credential asserts. Any storage associated with
this \fIname\fR must be freed by the application after use by a call to
\fBgss_release_name\fR(3GSS).
.RE

.SH DESCRIPTION
.sp
.LP
The \fBgss_inquire_cred_by_mech()\fR function obtains per-mechanism information
about a credential.
.SH ERRORS
.sp
.LP
The \fBgss_inquire_cred_by_mech()\fR function can return the following status
codes:
.sp
.ne 2
.na
\fB\fBGSS_S_COMPLETE\fR\fR
.ad
.RS 30n
Successful completion.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_CREDENTIALS_EXPIRED\fR\fR
.ad
.RS 30n
The credentials cannot be added because they have expired.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_DEFECTIVE_CREDENTIAL\fR\fR
.ad
.RS 30n
The referenced credentials are invalid.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_FAILURE\fR\fR
.ad
.RS 30n
The underlying mechanism detected an error for which no specific \fBGSS\fR
status code is defined.  The mechanism-specific status code reported by means
of the \fIminor_status\fR parameter details the error condition.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_NO_CRED\fR\fR
.ad
.RS 30n
The referenced credentials cannot be accessed.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_UNAVAILABLE\fR\fR
.ad
.RS 30n
The \fBgss_inquire_cred_by_mech()\fR function is not available for the
specified mechanism type.
